SYNOPSIS
#include <mqueue.h>

DESCRIPTION
The mq_getattr() function will obtain status information and attributes of the message queue and the open message queue description associ-
ated with the message queue descriptor.
The mqdes argument specifies a message queue descriptor.
The results are returned in the mq_attr structure referenced by the mqstat argument.
Upon return, the following members have the values associated with the open message queue description as set when the message queue was
opened and as modified by subsequent mq_setattr(3) calls: mq_flags.
The following attributes of the message queue will be returned as set at message queue creation: mq_maxmsg, mq_msgsize.
Upon return, the following members within the mq_attr structure referenced by the mqstat argument will be set to the current state of the
message queue:
mq_curmsgs The number of messages currently on the queue.
RETURN VALUES
The mq_getattr() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi-
cate the error.
ERRORS
The mq_getattr() function may fail if:
[EBADF] The mqdes argument is not a valid message queue descriptor.
